AB: In order to study the effect on the spatio-temporal distribution of earthquakes due to stress interactions, we select a faults system in Central Italy that includes causative faults of moderate to large magnitude earthquakes. The main parameters of each structure are confidently assessed. Then, we study the evolution through time of the faults system by modeling the seismogenic processes and the interaction among faults by means of co- and post-seismic stress variations. The evolution of this system under different initial conditions provides several synthetic catalogs of seismic events, whose spatio-temporal distributions give information on how interactions may affect the behavior of single or group of structures. We finally evaluate the changes in the probability of events on faults when a subset of them is not modeled, to estimate the possible consequences of missed faults.
